There are crucial issues to which the Torah devotes only an allusion, yet the story of finding a bride for Isaac consumes an entire chapter. Because this truly is the theme of all of Torah: The union of male and female energies, so that the world can operate in harmony. The union of heaven with earth. Of soul with body. Of your spiritual life with your business life. Of light and mystery. Of Creator and creation. There really is nothing else. And it all begins with harmony between husband and wife.
